The level of the acid DNase activity in the hemocytes and digestive gland of the mussel Mytilus galloprovincialis after exposure to model marine pollutants, a detergent, gasoline and a copper salt, as well as to unknown environmental mixture at selected sampling sites, was investigated. The specific enzyme activity in unexposed mussels from mariculture area(More)
The presence of neutral DNase activity in bivalves is reported for the first time. The enzyme activity in four tissues of the mussel Mytilus galloprovincialis was analyzed by three different methods (i) specific denaturating SDS-PAGE zymogram, (ii) sensitive single radial enzyme diffusion (SRED) assay and (iii) rapid and sensitive fluorimetric determination(More)
Mollusc haemolymph proteins are known to play several important physiological roles in the immune system, heavy metal transport and the tissue distribution of lipophilic compounds. In this study, we analysed acetone-extracted proteins from mussel haemolymph by one- and two-dimensional gel electrophoresis. The proteins were identified by comparing mass(More)
Cholinesterase (ChE, EC activity was investigated in gills and adductor muscle of two bivalve species: Arca noae and Venus verrucosa. The properties of ChEs were investigated using acetylcholine iodide (ASCh), butyrylcholine iodide (BSCh) and propionylcholine iodide (PrSCh) as substrates and eserine, BW254c51 and iso-OMPA as specific inhibitors.(More)
Acid DNase activity in marine organisms displays a sensitive response to pollutants. In the present study, ex situ effect of toxic seawater organic extracts (Rijeka, Vranjic, Ploče) and in situ impact of environmental factors at referent (St. Andrew) and a polluted site (ACI Rovinj) on acid DNase in the digestive gland and gills of mussels was investigated.(More)
The changes of acetylcholinesterase activity (AChE), metallothioneins content (MTs), catalase activity (CAT) and lipid peroxidation (LPO) were assessed after 4 days exposure of mussels Mytilus galloprovincialis to a wide range of sublethal concentrations of chlorpyrifos (CHP, 0.03-100 μg/L), benzo(a)pyrene (B(a)P, 0.01-100 μg/L), cadmium (Cd, 0.2-200 μg/L)(More)
In the present study, we investigated the progressive acclimation of the mussel Mytilus galloprovincialis to different reduced seawater (SW) salinities and its effect on several biochemical markers and biotests. Mussels were purchased from a local mariculture facility during summer (SW temperature 27 degrees C, salinity 37.5 psu) and winter (13 degrees C,(More)
